CHAN's relationship with the CTV network in the years prior to the realignment had been rocky. Historically, CHAN and some of the other affiliates in Western Canada had resented the dominance of the affiliates in the eastern part of the country, especially Toronto flagship CFTO-TV (channel 9), in the production of network programming, in regards to both entertainment shows and news programming.[3] The station had desired for years to host a national news program; when it was rebuffed by CTV, it instead launched the early-evening Canada Tonight on the WIC station group in 1993.[4]

These issues were exacerbated when the original owner of CFTO, Baton Broadcasting, which had been steadily buying out CTV affiliates across the country, took control of the network itself in 1997 and shortly thereafter revamped the CTV schedule to incorporate the programming of the former Baton Broadcast System. That same year, Baton launched a new Vancouver station, CIVT (channel 32, known on-air as "Vancouver Television" or "VTV").

Since CTV did not previously offer a network schedule covering the entire day (or even all of primetime), these changes meant that CTV now maintained two different programming streams: a base "network" schedule which aired on all CTV stations, both O&Os and affiliates, under the network's existing affiliation agreements; and a separate "non-network" block of programming which aired in its entirety on O&Os, although CTV would offer rights on a per-program basis to affiliates in markets where the company did not have a station of its own. In much of Canada, this was a meaningless distinction, as most CTV stations were already O&Os — but in Vancouver, the network programming aired on CHAN while the O&O programming aired on CIVT.

CHAN's Victoria-based sister station CHEK (channel 6) was itself a CTV affiliate and therefore carried the same stream of network programming as CHAN; however, since the Vancouver stations' footprint covered much of the Victoria area and vice versa, CTV network programs would usually air on CHEK on alternative nights and/or in different timeslots compared to CHAN.

This meant that for the four years between CIVT's launch and the 2001 realignment, CHAN and CIVT were effectively in competition with each other for programming to which CTV held the broadcast rights – the network sometimes reclassified programs from one stream to the other, possibly to help boost CIVT in the Vancouver ratings, in any event often leaving CHAN with little control over portions of its own program schedule. It was also widely expected, although not publicly confirmed by CTV until after Canwest announced its plans for CHAN, that the network would simply transfer all of its programming to CIVT when its affiliation agreements with CHAN and CHEK ended.

As a result of the WIC takeover, Global assumed ownership of CHAN and chose to retain it instead of its existing O&O CKVU-TV (channel 10), which had less transmitting power. Due to rules on media ownership set forth by the Canadian Radio-television and Telecommunications Commission (CRTC), which prohibit common ownership of two or more English language stations in a major market that have the same city of license, Global could not retain both stations simultaneously with CHEK in Victoria, so it put CKVU on the market. CKVU's sale to CHUM Limited for CA$125 million was announced on April 13, 2001,[5] and was approved by the CRTC on October 15 of that year.[6]

CHAN and CHEK's affiliation agreements with CTV were originally due to end in September 2000; in view of the uncertainty surrounding the local media landscape, CTV and Canwest renewed those agreements for an additional year, set to expire on September 1, 2001,[7] which became the date for the affiliation switch.

Launched in September 2001 as "NOWTV", rebranded in September 2005 as "OMNI 10", rebranded as "CHNU 10" in October 2007, and again as "Joytv 10" in September 2008

At the time, the only broadcast television stations in Vancouver and Victoria to be unaffected by the switch were CBC Television O&O CBUT and Télévision de Radio-Canada O&O CBUFT (CHNM-TV, currently part of the Omni Television system, did not sign on until 2003). Further complicating the situation were the launches of CHNU in Fraser Valley on September 15[8] and CIVI in Victoria on October 4,[9] which caused various changes to cable channel lineups within the region.

CKVU became a de facto Citytv station on the date of the affiliation switch, with its programming immediately provided and scheduled by CHUM Limited. However, as its sale to CHUM had not yet been finalized, the station was branded as "ckvu13" and did not officially adopt the Citytv brand name until 2002.[10]

The affiliation switch took place on September 1, 2001. However, as that date fell on the Labour Daylong weekend, some changes resulting from the switch (such as the new 5:00 to 7:00 a.m. timeslot for CIVT's morning newscast, for example) did not occur until September 4.

CHAN's local newscasts had historically been the overwhelming ratings leader in the Vancouver market, leaving CIVT's news team in the position – a rarity for CTV – of having to build a reputation and an audience against the market dominance of another station. To that end, CIVT recruited Bill Good and Pamela Martin from CHAN to serve as its primary anchor team. CIVT also adopted "BC CTV" as its on-air branding; it is widely believed that this brand name was deliberately chosen to confuse viewers, as CHAN had previously been branded "BCTV" and continued to call its news operation BCTV News on Global until 2006 (although CHAN began to de-emphasize the hybrid branding in 2003). CIVT changed its on-air brand to simply "CTV" exactly ten months later on July 1, 2002; "CTV British Columbia" (or, occasionally, "CTV9," in reference to CIVT's channel number on most Vancouver area cable providers) is used where disambiguation from the network or other CTV O&Os is warranted.

CIVT's news ratings rose significantly: the station's 6:00 p.m. newscast attracted around 36,000 viewers in 2002;[11] that number improved to 72,000 viewers by December 2010,[12] and occasionally reaches as high as 100,000,[11] though still well behind that of CHAN's 303,000 viewers from the same period.[12] CIVT effectively became Vancouver's second-place television news operation, replacing CKVU, which lost approximately half of its audience and dropped to last place when it adopted the CityPulse format. CKVU's newscasts continued to struggle in the ensuing years, and the 6:00 and 11:00 p.m. newscasts were cancelled in 2006, ahead of CHUM's merger with CTVglobemedia[10][13] and the subsequent sale of the Citytv stations (including CKVU) to Rogers Media in 2007[14] (CKVU continues to produce Breakfast Television, which was launched in 2002 in conjunction with the Citytv brand).

the integration of the former WIC-owned independent stations CHEK, CHCH (in Hamilton) and CJNT (in Montreal) into the CH television system; and

the transformation of Citytv from a single independent station in Toronto into a full-fledged television system.

CHAN had – and continues to have – a much larger network of rebroadcasters than CIVT, meaning that CTV lost almost all of its terrestrial coverage in British Columbia outside of the Greater Vancouver and Victoria area, and to this day still relies on cable television, not terrestrial transmitters, to reach most of the province. This gave a significant boost to Global, and a corresponding handicap to CTV, in the national television ratings during the early 2000s. However, with CTV generally outspending Global on hit television series over the next number of years, and continuing reductions in the number of viewers relying solely on over-the-air broadcasts, this advantage had largely dissipated by 2006. As a consequence of continuing reductions of over-the-air-viewers, CBUT shut down its network of rebroadcasters in 2012, although that was the result of budget cuts to the CBC.

The realignment also had some effects in the United States, where Bellingham, Washington station KVOS-TV (channel 12), which had previously carried some Citytv programming due to its proximity to Vancouver, lost this programming source now that Citytv had its own station in the market. KVOS was also displaced from its prime position on cable providers in both Vancouver and Victoria to make room for CIVI,[9] causing the station to lose significant market share in British Columbia.

Kevin Newman, then working for ABC News, left that network and returned to Canada as the anchor and executive editor of Global National; he held both positions until leaving Global in 2010.
